commit50dce2e2f8upstream. The LTC3676_IRQSTAT_* bit definitions do not match the IRQSTAT (Interrupt Request Status) register layout documented in Table 15 of the LTC3676/LTC3676-1 datasheet: bit 0 - Pushbutton Status Active bit 1 - Hard Reset Occurred bit 2 - PGOOD Timeout Occurred bit 3 - Undervoltage Warning bit 4 - Undervoltage Standby (Fault) Occurred bit 5 - Overtemperature Warning bit 6 - Overtemperature Standby (Fault) Occurred bit 7 - Reserved The driver instead defines these starting at bit 3, one bit higher than the datasheet specifies, which causes ltc3676_regulator_isr() to check the wrong status bits and misreport (or miss) PGOOD timeout, undervoltage and thermal warning/fault conditions. Fix the bit offsets to match the datasheet.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
